1. What is Resultant Reaction on Bearing 2?

The Resultant Reaction on Bearing 2 of a centre crankshaft at the angle of maximum torque represents the total reaction force acting on the second bearing. This force is the vector sum of all vertical and horizontal forces acting on the bearing, including those from radial forces, flywheel weight, tangential forces, and belt tensions.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ R2 = \sqrt{(R2v + R'2v)^2 + (R2h + R'2h)^2} \]

Where:

\( R2 \) — Resultant Reaction on CrankShaft Bearing 2 (N)
\( R2v \) — Vertical Reaction at Bearing 2 Due to Radial Force (N)
\( R'2v \) — Vertical Reaction at Bearing 2 Due to Flywheel (N)
\( R2h \) — Horizontal Force at Bearing2 by Tangential Force (N)
\( R'2h \) — Horizontal Reaction at Bearing 2 Due to Belt (N)

Explanation: The formula calculates the magnitude of the resultant force by taking the square root of the sum of squares of the total vertical and horizontal force components.

3. Importance of Resultant Reaction Calculation

Details: Accurate calculation of the resultant reaction force is crucial for proper bearing selection, structural analysis of the crankshaft, and ensuring the mechanical integrity of the engine system under maximum torque conditions.

4. Using the Calculator

Tips: Enter all force values in Newtons (N). Ensure all values are non-negative. The calculator will compute the resultant reaction force using vector addition principles.

5. Frequently Asked Questions (FAQ)

Q1: Why is the angle of maximum torque important?
A: The angle of maximum torque represents the condition where the crankshaft experiences the highest torsional loads, making accurate bearing reaction calculations critical for design and safety.

Q2: What are typical values for these reaction forces?
A: Force values vary significantly based on engine size, design, and operating conditions. Consult engine specifications for typical values.

Q3: How does flywheel weight affect the resultant reaction?
A: Flywheel weight contributes to the vertical reaction force component, increasing the overall resultant force on the bearing.

Q4: Are there any limitations to this calculation?
A: This calculation assumes static conditions and may need adjustment for dynamic effects, vibration, and other real-world factors in engine operation.

Q5: How is this result used in engineering practice?
A: The resultant reaction force is used to select appropriate bearings, design bearing housings, and verify the structural adequacy of the crankshaft system.
